Definitions
- the present invention relates to a method for dyeing of textile polyester or textile materials containing polyester with navy blue amino azo dyes.
- polyester is polyester or polyester-containing Textile materials with disperse dyes aqueous dye bath under HT conditions in a temperature range colored from 120 to 140 ° C at pH values from 4 to 6, because at higher pH values the disperse dyes partially or completely destroyed. At higher pH values This leads to loss of color strength and color deviations when dyeing and the dyeings are not reproducible.
- the polyester fiber in a separate step before staining an alkaline Subject to rinsing treatment to aids that have been used in weaving or spinning the fiber, to remove.
- These tools are e.g. Oiling or Sizing agents that, when available, are level Dyeing the polyester fiber difficult or impossible would do.
- the alkaline treatment is also carried out to oligomers of polyester fiber that are used in the dyeing process have emerged from the inside of the fiber and the Color uneven, destroy and appear in the to keep aqueous dye liquor.
- the oligomers mentioned are particularly undesirable in yarn dyeing because they itself when spinning the dyed yarn in the spinning apparatus where the yarn is deflected by abrasion settle powdery. This will contaminate the equipment and cause the yarn to tear.
- This alkaline rinsing treatment is convenient performed at elevated temperature. For time and energy to save and the number of alkaline for both processes Pretreatment and dyeing, equipment needed reduce, it has always been the goal of both processes to form a one-bath rinsing and dyeing process. However, procedures must be implemented to achieve this goal be developed in an aqueous dyebath at pH 8 reproducible colorations up to pH 11.
- Polyester-cellulose or polyester-polyamide blend are with disperse or reactive dyes from aqueous Dye bath usually dyed in two dyeing steps.
- the goal here in the past was a one-bath Develop application methods for both dye classes. They searched for reactive dyes which are already colored at pH values between 8 and 11 and procedures were also required who ensure that under these conditions the Polyester content reproducible with disperse dyes can be colored.
- DE-A 39 38 631 describes a method in which disperse dyes in the pH range between pH 8 and 10 in Presence of at least one, optionally on nitrogen substituted amino acid and / or an alkali metal salt one optionally substituted on nitrogen Amino acid can be colored.
- Blue cyanazo dyes are already known from EP-A 540 936 known with which polyester or polyester-containing fiber materials according to the HT method in the pH range between 8 and 11 can be colored. Possess these dyes high pH stability, but pull when dyeing badly, so that with them no deep navy blue Colorings can be obtained. They also show Dyes defects in the levelness of the dyeings and in the sensitivity to copper ions in the dyeing water can be included. Furthermore, meet not all of them in terms of their fastness to use Conditions.
- R standing for (C 2 -C 5 ) alkyl can be straight-chain or branched and means, for example, ethyl, n-propyl, i-propyl, n-butyl, i-butyl, sec-butyl, n-pentyl, i-pentyl or sec-pentyl.
- R (C 3 -C 5 ) alkyl is preferred.
- Preferred dyes of the general formula 1 to be used according to the invention are those in which X is methoxy or ethoxy.
- the process according to the invention can be carried out using a dye of the general Formula I run. But it can also be used with two or more Dyes of the general formula I are carried out, but two or three dyes are preferred.
- the proportion of a dye in these cases is preferably 5 to 95% by weight, particularly preferably 20 to 70% by weight, each based on the total amount of dye.
- Mixtures which contain at least one dye, in which X represents hydrogen and at least a dye in which X represents methoxy or ethoxy, contain.
- Particularly preferred mixtures contain a preferred one Dye of the general formula I.
- Very special preferred mixtures contain two or more preferred Dyes of the general formula I.
- the dyes of the general formula Ia can be prepared analogously to the processes described in the abovementioned prior art.
- they can be prepared by an amine of the general formula II wherein Hal is as defined above, diazotized in a conventional manner and on a compound of general formula III where R and X are as defined above, is coupled.
- the process according to the invention is preferred under HT conditions executed, i.e. in aqueous dye liquor Temperatures between 120 ° C and 140 ° C in a dyeing autoclave.
- the pH value is preferably pH 9 to pH 10.
- the dyes of the general formula according to the invention Ia can not only in the inventive method, but also in other common processes for dyeing and Printing of hydrophobic synthetic textile materials, e.g. under HT conditions in the pH range between 4 and 11 or in the so-called thermosol process be or after a printing process on the fiber be applied.
- Polyesters are in particular those based on polyethylene glycol terephthalates. Textile materials containing polyester are e.g. Mixtures of polyester and polyamides.
- the dyes or dye mixtures used in fine distribution takes place in a manner known per se Wise in that the one arising in the manufacturing Dye together with dispersants in in a liquid medium, preferably in water and the mix of shear forces exposes the original dye particles mechanically crushed to the extent that a optimal specific surface is achieved and the Sedimentation of the dye is as low as possible.
- the Particle sizes of the dyes are generally between 0.5 and 5 ⁇ m, preferably around 1 ⁇ m.
- the dispersants used in the grinding process can be nonionic or anionic.
- Non-ionogenic Dispersants are e.g. Reaction products of alkylene oxides, such as. Ethylene or propylene oxide with alkylatable Connections such as Fatty alcohols, fatty amines, Fatty acids, phenols, alkylphenols and carboxamides.
- Anionic dispersants are, for example Lignin sulfonates, alkyl or alkyl aryl sulfonates or alkyl aryl polyglycol ether sulfonates.
- the dye preparations thus obtained are intended for most applications are pourable.
- the dye and The dispersant content is therefore limited in these cases.
- the dispersions are in one Dye content up to 25% by weight and a dispersant content set up to about 25%. From economic Dye contents of 15% by weight are usually not the reason undershot.
- the dispersions can also contain other auxiliaries, e.g. those that act as oxidizing agents, such as e.g. Sodium m-nitrobenzenesulfonate or fungicidal agents, such as. Sodium o-phenyl phenolate.
- auxiliaries e.g. those that act as oxidizing agents, such as e.g. Sodium m-nitrobenzenesulfonate or fungicidal agents, such as. Sodium o-phenyl phenolate.
- These powders contain the dye or that Dye mixture, dispersant and other auxiliaries, such as. Wetting, oxidation, preservation and Dedusting agent.
- a preferred manufacturing method for powdery Dye preparations are that described above liquid dye disperses the liquid is withdrawn, e.g. by vacuum drying, freeze drying, by drying on drum dryers, preferably but by spray drying.
- the necessary Amounts of dye settings made according to the were made with the coloring medium, preferably diluted with water to such an extent that for de coloring a liquor ratio of 1: 5 to 1: 50 results.
- the fleets are generally more Dyeing aids, such as dispersing, wetting and Fixing aid added.
- the required pH value of the dye liquor is checked before or also during dyeing by adding bases such as alkali hydroxides, e.g. aqueous sodium hydroxide solution, alkali hydrogen carbonates, e.g. Sodium bicarbonate or alkali carbonates e.g. Soda, discontinued.
- bases such as alkali hydroxides, e.g. aqueous sodium hydroxide solution, alkali hydrogen carbonates, e.g. Sodium bicarbonate or alkali carbonates e.g. Soda, discontinued.
- buffer substances are preferably added, as described, for example, in JSDC 77 (1979), p. 47 or JSDC 79 (1981), p. 115.
- Particularly suitable buffer substances are those which have the greatest buffering action in the pH range between 9 and 11.
- Suitable buffer systems are, for example, acetic acid / sodium pyrophosphate, boric acid / borax, sodium dihydrogen phosphate / disodium hydrogen phosphate, phosphoric acid / succinic acid / boric acid or combinations of organic phosphorus compounds with polycarboxylic acids.
- the amounts of buffer system used are preferably between 0.5 and 10 g / l.
